10	Articulated swing	US306303	1994-09-14	US5505664A	1996-04-09	Robert J. Nolan; Paul C. Gilles
A children's swing ride is composed of an articulated seating platform having an axis of articulation. A pair of hangers is connected to the seating platform on opposite sides of that axis and a pair of levers extends from the platform on opposite sides of that axis. In use, the platform is suspended by way of the hangers from an overhead support so that riders sitting on opposite ends of the platform can swing back and forth and, by exerting force on the other rider's lever, cause articulation of the seating platform.
11	Tandem swing	US30667	1993-03-12	US5393268A	1995-02-28	Joel C. Cunard; Robert J. Boudreau
A children's swing has an elongated beam with opposite ends and a mid portion providing a seating platform for at least two children. Pivotally attached to the opposite ends of the beam are a pair of rigid rockers, each rocker having an upper end defining hand grips and a lower end defining a foot rest. To use the rocker, the children sit on the beam back to back with their hands and feet on the hand grips and foot rests of the rockers in front of them. When the children rock the rockers in synchronism, the swing will swing to and fro with ever increasing amplitude due to the inertia of the children's limbs and changes in the included angles between the rockers and the beam.
